Vectra C - Steering wheel with exclamation mark and c1532-05 error

I've been struggling with the topic for a long time ... In general, support comes. Replaced CIM (because it was broken sas) helped, the traction control went out, directions reflect.
Only the steering wheel was left with an exclamation mark and error c1532-05. The previous owner replaced the pump and the TRW pump sits with two cables and two end caps. The fluid is, all pins are psyched by contact, in the pump included esp and yrs.
Is Pompe somehow programming? Is it just how to configure CAN in opcom?
Does the signal that is missing causing the error c1532, goes from the pump straight to CIM?

... Unsuitable pump installed, this can be corrected with a dedicated diagnostic device.
The pump is being programmed.

Programming the pump techem2 will do the trick

So opcomem / vaucomem ream will not move the topic?

I did op comem

Ie. did you cancel the c1532-05 error? Could you describe something more or less?

rather, he doubts because a colleague tried the opcom and did not give advice until the tech changed configuration
